How to Anchor Veins

Rolling Veins in a Hand

Drawing blood or inserting an IV can be challenging, especially when dealing with clients who have rolling veins.

To address this issue, nurses must know how to anchor veins safely. But before diving into the steps, it’s important to understand what rolling veins are and why they happen.

What Does it Mean if Your Patient Has Rolling Veins?

Rolling veins move or “roll” away when you attempt to insert a needle.

They’re also known as “mobile veins” or “slippery veins.” This can make venipuncture more difficult and sometimes uncomfortable for the patient.

Why Do Veins Roll?

Veins may roll due to several factors, such as the:

  • Elasticity of the skin and vein walls: A client may naturally have veins closer to the skin’s surface, making them more prone to rolling.
  • Positioning of the arm or hand: If a patient unintentionally moves their arm or hand during venipuncture, it can cause the vein to roll.

Why Are Some Veins Hard to Draw Blood From?

Several factors can make veins difficult to draw blood from.

  • Nurses may find it challenging to locate small or deep veins.
  • Veins used frequently for blood draws or IVs can develop scar tissue, making them harder to puncture.
  • Anxiety can cause veins to constrict, making them smaller and more challenging to work with.

Understanding these factors can help nurses better anticipate and manage difficult venipuncture situations.

Are Rolling Veins Genetic?

While external factors like body fat and hydration can influence whether a client has rolling veins, there’s also a genetic component.

A client may naturally have veins more prone to rolling due to the structure and elasticity of their walls or surrounding tissue. If a client has a family history of difficult veins, they might experience similar challenges.

Steps to Anchor Veins Safely and Effectively

To learn how to prevent rolling veins during venipuncture, follow these steps:

  1. Wash your hands and put on gloves. This reduces the risk of infection.
  1. Ensure the patient is well-hydrated and relaxed. This promotes vein stability and visibility.
  1. Choose a vein that feels stable and less likely to roll. Consider factors like accessibility, location, and size when selecting a vein for the procedure.
  1. Prepare the site. Warm the area to increase vein visibility and elasticity.
  1. Position the client’s arm in a comfortable and stable position. Use a pillow or armrest if needed to keep the army steady.
  1. Place a tourniquet about 4-5 finger widths above the puncture site. This will help engorge the veins, making them easier to see and feel.
  1. Palpate the vein. Feel for the size, direction, and depth of the vein.
  1. Apply gentle pressure. Use the fingers of the non-dominant hand to secure the vein in place, preventing it from rolling during needle insertion.
  1. Anchor the vein. Anchoring the vein involves stretching the skin taut below the puncture site by pulling it away from the direction of the needle insertion.
  1. Insert the needle. Hold the needle at a shallow angle (15-30 degrees with the bevel up) and insert it swiftly into the vein.
  1. Secure the needle. Once in, stabilize the needle and proceed with the IV insertion or blood draw.
  1. Comfort the client. Communicate with the client during the procedure to make sure they’re relaxed.

I cannot express enough gratitude for Nurse Mike and this wonderful platform he has created. I had a subscription to SimpleNursing the entire 2 years of my nursing school career and it was the best resource I had available to me. The visuals, the explanations, the memory tricks, the songs, the study guides, and the test questions are brilliant.

Before starting nursing school, I was a C-average student. I didn't think I'd be competent enough and make it through my second semester. I was told about SimpleNursing and purchased it immediately. Long story short, I graduated nursing school with honors and passed all of my classes with As and Bs only. I would have never been able to do that without the help of SimpleNursing. Nurse Mike teaches in the only way that I am able to learn and I cannot thank him enough.
